2021 Child Tax Credit: Here’s who will get up to $1,800 per child in cash — and who will need to opt-out

About 36 million American families on July 15 will start receiving monthly checks from the IRS, as part of the expanded Child Tax Credit. Eligible families will receive up to $1,800 in cash through December — however, the tax credit has a complication that may prompt some families to opt out. 

The enhanced Child Tax Credit (CTC) was signed into law by President Joe Biden as part of the American Rescue Plan. The effort expands the benefit from a $2,000 credit, taken annually when you file your taxes, to up to $3,600 per child, with halfthe amount divided into six payments to be paid out in cash, on a monthly basis, from July through December, and the rest claimed on your 2021 tax return.

The Biden administration has proposed extending the monthly payments for five more years, White House Press Secretary Jen Psaki told "CBS This Morning" on Monday.

"He thinks this is a central benefit that will help families, help get women back to work," Psaki said, noting that more that a million women have left the workforce during the pandemic.

The effort has some similarities to the three rounds of stimulus checks that have been distributed by the IRS to help people weather the pandemic. For one, the enhanced CTC and the stimulus checks are only available to eligible lower- and middle-class families, with upper-income households essentially shut out of the benefit. And secondly, the IRS will deposit the payments directly into bank accounts. 

But there is one major difference between the stimulus checks and the enhanced CTC in how the IRS treats overpayment. With the stimulus checks, recipients didn't have to repay the IRS if they received more than they were entitled. That's not the case with the enhanced Child Tax Credit. 

"If you are getting money and don't qualify, you need to opt out of it," said Mark Steber, Jackson Hewitt's chief tax information officer. "You will have to pay that money back."

In contrast, the stimulus payments' treatment of overpayment amounted to "a big 'Get out of jail' card," he said.

The IRS last week flagged the overpayment issue: "If you receive a total amount of advance Child Tax Credit payments that exceeds the amount of Child Tax Credit that you can properly claim on your 2021 tax year, you may need to repay to the IRS some or all of that excess payment," it said on its website.

Who qualifies for cash payments?

Under the American Rescue Plan, the CTC was expanded to $3,600 for each child under age 6 and $3,000 for each child between ages 6 to 17. Previously, the credit had excluded children who had turned 17 and was limited to $2,000 per child.

Aside from having children who are 17 or younger as of December 31, 2021, families will only qualify for the expanded credit if they fall below certain income thresholds:

• $75,000 or less for single taxpayers
• $112,500 or less for heads of household
• $150,000 or less for married couples filing a joint return and qualified widows and widowers

What if I have kids but my income is above that?

Families may still receive some of the enhanced tax credit if they earn above those thresholds — up to a point. Families will receive $50 less for every $1,000 over an income threshold, until the enhanced payments are phased out for people who earn roughly $20,000 more than those salary thresholds.

In other words, single filers who earn up to $95,000 and married couples with combined incomes up to $170,000 would receive smaller payments, but above that they would be phased out entirely from the enhanced Child Tax Credit. 

However, families who earn above those phase-out caps may still qualify for the regular Child Tax Credit. The regular CTC of $2,000, taken annually on your tax return, is available to single parents who earn up to $200,000 and married couples who earn up to $400,000. Higher-income families who earn above those income thresholds don't qualify for either the regular CTC or enhanced CTC.

How much will I get for each child? 

For parents, the payments will amount to:

• $300 per month for each child under 6
• $250 per month for each child between ages 6 and 17

That means that a qualifying family with two parents who file a joint tax return and have two children under 6 will receive $600 in monthly payments for six months, starting July 15 and ending December 15. Over the course of the period, they'll receive $3,600 in cash from the IRS for their two children.

What should I do to get the money?

Typically, nothing, said Steber of Jackson Hewitt.

"They have to do nothing if their situation was the same as their 2020 tax return — if their address is the same, their bank account is the same, same number of dependents," Steber said.

The IRS already sent letters to 36 million families who are eligible based on either their 2019 or 2020 federal income tax return, or if they provided information using the "non-filers tool" on the IRS.gov website last year to register for a stimulus payment and qualified based on that data. 

The IRS said it will soon send a second letter that will estimate eligible families' monthly payment, which will begin hitting millions of bank accounts on July 15. 

What if I'm a non-filer?

Because the IRS relies on tax returns to determine the enhanced CTC, some people may fall through the cracks, such as low-income households that aren't required to file tax returns.

In that case, the IRS has opened a portal for those families to register for the tax credit. That portal can be found here.

The IRS says that non-filers will need to provide personal information such as their date of birth, as well as Social Security numbers for themselves and their children. If they have a bank account, they can also enter the bank routing number and bank account number to receive deposits.

What should I do to opt out?

Because the IRS is relying on tax returns to determine payments, it sometimes doesn't have the most up-to-date information about taxpayers, such as their latest income or number of children. 

That could result in some taxpayers either receiving the cash payments when they aren't actually eligible, or some people receiving less than they are entitled to — such as if they had a child in 2021, which the IRS wouldn't be aware of since it's looking at either 2020 or 2019 tax returns for eligibility. 

The problem with overpayment is taxpayers will be required to repay any money received. That could happen if, for example, your 2020 income during the pandemic qualified you for the enhanced CTC, but your 2021 income was higher and would disqualify you. In that case, you could be looking at a future bill from the IRS. 

The IRS said people will be able to opt out via an online tool, which isn't yet available but should be on the IRS' website by the end of June. Called the Child Tax Credit Update Portal, the tool will allow people to un-enroll from the tax credit before the first payment is made on July 15. 

Can the Child Tax Credit payments be garnished?

Yes, according to the IRS. 

The payments can be garnished by a number of creditors, including state and local governments and private creditors. However, some states and financial institutions have decided to shield their constituents and customers' CTC from garnishment, the IRS said. 

For instance, California's attorney general recently said it is illegal for creditors to garnish CTC payments made to the state's residents.

Will the CTC payments be reduced for federal back taxes?

No, the IRS said. 

The IRS won't chip away at your monthly payments to cover federal taxes that you may still owe. However, the IRS warned that if you get a refund when you file your 2021 taxes, any remainder amount from the CTC that is included in the refund could be used to offset tax debts.
